2021年7月23日 · Mitral valve (MV) dilatation by balloon catheter also known as percutaneous transcatheter mitral commissurotomy (PTMC) is now recognized as the treatment of choice to relieve rheumatic mitral stenosis (MS) in patients with suitable valve anatomy. Dr. Kanji Inoue first developed PTMC in 1982.

2021年5月28日 · Introduction of percutaneous transvenous mitral commissurotomy (PTMC) by Inoue in 1984 for the treatment of selected MS patients has transformed the treatment of MS. Other names for PTMC include percutaneous balloon mitral valvotomy (PBMV) or valvuloplasty.

Percutaneous trans-mitral commissurotomy (PTMC) is the standard of care in managing severe rheumatic mitral stenosis (MS). This article reports a single-center, 10-year real-world experience in Qatar. In this retrospective study, we reviewed all the patients who underwent PTMC in Qatar between January 1, 2012, and January 1, 2022.

Aim: Patients with severe mitral stenosis (MS) and their clinicians typically choose percutaneous transvenous mitral commissurotomy (PTMC) over surgical commissurotomy (SC). However, the durability of PTMC relative to SC is uncertain. We compared the efficacy, safety and durability of PTMC with SC for the treatment of MS.

Percutaneous Trans-Mitral Commissurotomy, is a procedure done for a cardiac pathology called MITRAL STENOSIS. Mitral stenosis is a pathology of one of the valves in the heart called the Mitral valve, where-by it undergoes progressive thickening resulting from child hood throat infection by a bacteria called Beta Hemolytic Streptococci.

Based upon the nature and severity of MS, patients can be managed with medical management, percutaneous transvenous mitral commissurotomy (PTMC) or surgery. PTMC has revolutionized the treatment of patients with symptomatic MS and is now established as the procedure of choice.
